since your a big guy,
I would strongly suggest you cruise over to the Triumph dealer,
get a ride on a Rocket III,
you will be amazed at how balanced it is once the wheels start rolling.
Moreso than the HD.
That said make sure your holding on before you twist the throttle,
as the bike may try to come out from under you,
the shaft drive works well
great brakes and handling to match,
Not much will be able to keep up if your on the pipe,
though its not a canyon scratcher it does have more lean then the HD baggers,
you can find low mile versions for under 7K,
SRSLY try one
